Unsupervised segmentation of words into morphemes -- Challenge 2005

Part of the EU Network of Excellence PASCAL Challenge Program. Participation is open to all.

The objective of the Challenge is to design a statistical machine learning algorithm that segments words into the smallest meaning-bearing units of language, morphemes. Ideally, these are basic vocabulary units suitable for different tasks, such as text understanding, machine translation, information retrieval, and statistical language modeling.

The scientific goals are:

The results will be presented in a workshop arranged in connection with other PASCAL challenges on machine learning.

Please read the rules and see the schedule. The datasets are available for download. Instructions on how to submit your camera-ready documents are given on the Workshop page.

We are looking forward to an interesting competition!
